Why is IIS 6 / Windows 2003, forcing a Website to use .NET 2.0?

I have a Windows 2003 Server 64bit running IIS 6.0.

When I set the server up, I noticed that the 'ASP.NET' tab has been removed from the 'Web Sites' property in IIS Manager.

Now every website runs on .NET 2.0 and I need to change them to run on .NET 4.0.
I have ASP.NET 4 (32bit) enabled in the 'Web Service Extension' (the only other options ASP.NET versions 2 in both 32 and 64 bit modes).

I can confirm that in C:\Windows\Microsoft.net folder, there is both 'WOW' and 32bit .Net installation.

This is a production server with many websites and I'm afraid to run some IISReg scripts to put back the 'ASP.NET' tab.

When I try to the .Net 4 targeted website, I get an error:

Unrecognized configuration section system.web.extensions

The version information shows .Net 2.0

So what can I do?
Thanks!

As I indicated in my 'Comments' above, I had to run IIS in 32bit mode in a 64 bit system to target a certain web application. The background information for that can be see here:

That resulted in running all websites in 32 bit mode with .NET 2.0. To get the new web application to run in .NET 4, I followed instructions, per:

Problem solved! FYI. Thanks.
